Product Overview
Its optical system achieves extremely low geometric distortion controlled strictly at 0.05%, and delivers outstanding resolution performance (max 250 lp/mm at the axis, 160 lp/mm at edge). Supporting a maximum object field of view up to Φ3000mm, this lens eliminates perspective parallax completely via dual-side telecentric optical design, making it the ideal core imaging component for ultra-wide web, large flat panel and oversized sheet metal automated inspection lines in new energy, display, PCB, printing and automotive industries.
Distinctive Core Product Features
- Dual-Side Bi-Telecentric Optical Design, Zero Parallax Measurement Deviation
Parallel chief ray design on both object and image sides locks stable fixed magnification regardless of vertical jitter or slight tilt of conveyed workpieces within depth of field. It fundamentally removes parallax-induced measuring errors, guaranteeing repeatable sub-pixel dimensional accuracy for strict industrial metrology.
- Ultra-Low Distortion ≤0.05%, Authentic Geometric Restoration
Advanced full-aperture aberration correction limits full-field distortion to only 0.05%, far exceeding conventional telecentric lenses. Every edge contour and micro feature is reproduced without stretching, compression or deformation, greatly improving the stability of edge extraction by vision measurement algorithms.
- Optimized for 16K 3.5μm Ultra-Fine Pixel Line Scan Sensors
High MTF optical performance up to 250 lp/mm at the center fully matches 3.5μm ultra-small pixel 16K line scan cameras, capturing micro scratches, tiny pinholes and subtle dimensional tolerances across the full ultra-wide scanning width without detail loss at image edges.
- Adjustable F4.5–F22 Stepless Iris for Versatile Industrial Lighting
Wide adjustable aperture balances light throughput and depth of field flexibly. Large F4.5 aperture boosts exposure for dim low-reflectivity materials; narrow F22 extends DOF to adapt uneven-height workpieces, compatible with coaxial line lights, diffuse dome lights and linear array lighting systems.
- Ultra-Wide Working Distance Range (834–3050mm) & Massive FOV Capacity
Supports ultra-long object distance layout for large automated production equipment, and provides multiple calibrated FOV options up to Φ3000mm. Single lens replaces multi-camera stitching systems, cutting hardware investment and simplifying mechanical fixture design for meter-level oversized workpieces.
- Rugged Lockable All-Metal Industrial Housing with M72 Standard Mount
Robust eco-friendly metal lens barrel comes with dedicated locking screws for aperture and focusing rings to prevent parameter drift from factory vibration and temperature fluctuation. Universal M72 threaded mount fits all mainstream 16K line scan camera brands for seamless equipment integration.
- Uniform Full-Field Illumination & Broadband Anti-Reflection Coating
Optimized vignetting correction ensures consistent brightness from image center to extreme edge, eliminating dark corners and reducing image pre-processing workload for vision software. Broad-spectrum AR coating delivers high contrast imaging for white, blue and near-infrared industrial illumination.
Most Important Core Functions
- Ultra-Large Workpiece High-Precision Non-Contact Dimensional Metrology
Accurately measure length, width, hole pitch, flatness and outline tolerance of oversized glass substrates, aluminum extrusions, solar panels, lithium battery pole sheets and large automotive sheet metal. Constant magnification eliminates parallax deviation to output stable, repeatable measuring data.
- Blind-Zone-Free Full-Width Continuous Roll-to-Roll Defect Inspection
Capture complete surface information in a single scan for printing films, textile fabrics, plastic foils and coating webs. Reliably detect micro scratches, pinholes, stains, coating unevenness and printing offset across the entire ultra-wide field of view, removing the cost and complexity of multi-camera stitching solutions.
- Stable Long-Run High-Speed Inline Automated Production Imaging
Strong depth-of-field tolerance adapts minor vertical fluctuation of moving materials during high-speed conveying. The rigid optical-mechanical structure maintains consistent imaging quality for 24/7 non-stop mass production, lowering equipment downtime caused by frequent lens re-calibration.
- High-Fidelity Contour Restoration for Automated Sorting & Robot Guidance
Ultra-low distortion truly restores the original geometric profile of large-format parts, supporting high-precision contour matching, automatic dimensional sorting and robot visual positioning for assembly and machining production lines.
- Universal Compatibility with Global Mainstream Machine Vision Ecosystems
Standard M72 mount matches all mainstream 16K line scan camera models; captured images are fully compatible with Halcon, VisionPro, OpenCV and other mainstream image analysis software, reducing secondary development difficulty for system integrators.
